I am using the following source (diff for microwin is attached):
micrown (Nano-X)
nxlib latest git source
LibVNCServer-0.9.9
freetype-2.4.8
The attached diffs contain changes to get VNC to link properly, but also some
customization
for my application (paths, no VNC passwd, version timestamp, UTF-8 support and
debug messages)
VNC is connecting and mostly working. The issue I have is small screen image
changes
do not get updated. The only way to get those changes is to wait for a large
change or
hit the refresh button on the VNC client.
I assume you're running the latest (git) microwindows source.
Are you testing this on X11 or a framebuffer device?
If so, the reason that you're likely not getting screen updates is that
the new blit routines don't update automatically, they require a
call to the psd->Update() procedure with the coordinates of the
screen that have been modified. If you look at some of the routines
in engine/convblit*.c, you'll see how this is used.
Thus, in your driver, after performing the draw code, you'll want to
call psd->Update with the bounding rect of the areas modified.
There is the possibility this is not the issue, but this is definitely required
when using X11 or non-framebuffer due to the new drawing architecture with
backing store. I haven't looked at your changes yet, as I'm still buried at
work.

Greg

I am using framebuffer. I'll let you know if calling psd->Update() helps.
Thanks,
